Can't get into The Story of Edgar Sawtelle

Everybody said I should read The Story of Edgar Sawtelle. It's about dogs. It's set in Wisconsin. It was Amazon's Book of the Month in June 08. So how come my bookmark it stuck at page 90? Why do I walk past the book every day and reach for something else? Maybe it's ADD - I need too much stimulation and this book unfolds verrrrry slowly. What do YOU think?
